I think that the Bible as literature should be a compulsory part of the national curriculum.. you can't understand English literature and culture without it. But insofar as theology studies the nature of the divine, it will earn the right to be taken seriously when it provides the slightest, smallest smidgen of a reason for believing in the existence of the divine. Meanwhile, we should devote as much time to studying serious theology as we devote to studying serious fairies and serious unicorns.
